High-quality reaming drill bits can generally meet various geological conditions. As long as the driller can strictly follow various construction procedures, it can be guaranteed. In the long-term operation, the performance can still be guaranteed. After all, The design scheme of the Reaming Bit is to use reaming cones and a cone-shaped pyramid structure to achieve the effect of crushing stone particles and cutting rocks through rows of inlaid steel teeth.
When replacing a new reaming bit, it is necessary to run in with the drilling for a period of time, and when it reaches a distance of one meter from the bottom of the well, start drilling with steady pressure, and do it immediately after poor drilling and skip drilling. If the drilling depth is shallow, you can immediately trip out to observe whether the drill bit is damaged.
In the process of using the reaming bit, try to increase the water flow as much as possible. The higher the pressure of the water flow, it can ensure that a certain rock breaking effect can be achieved. At the same time, it can bring out some small stones, which can reduce the size of the reaming bit. Drilling resistance to improve the efficiency of drilling.
